Heads up - we are investigating issues with the US, EU, and AU - more to come shortly. Check https://status.knack.com/ for updates
In the US and EU regions, the Knack Builder and website (www.knack.com) are unavailable. The Live Apps should still be functional in all regions.
4:10 pm PT: We have re-enabled access to the Knack Builder. There may be intermittent slowness.
We are still actively working on a solution to the original issue.
